I Can't start Jenkins in background (Address already in use)

I am running jenkins using 

java -jar jenkins.war -httpPort=31114

and it starts correctly, Now I am trying to run it in background, I found it can be done using nohup java -jar jenkins.war -httpPort=31114 & as mentioned here Start Jenkins in the background.

But when I terminate the session I started at the beginning and try to run it in background on the same port, I get the following error:

It means jenkins already running on given port or some other process is using that port.

netstat -nltp Use this command to check all open ports. Kill process if jenkin allready running on that port or if other process is using that port you can run jenkins on other port.

Below commnd you have used is correct . May be you have hit it twice .

nohup java -jar jenkins.war -httpPort=31114 &

ps -ef | grep jenkins. To check if jenkins is already running.
